Question

You wish to make a 0.136 M perchloric acid solution from a stock solution of 6.00 M perchloric acid. How much concentrated acid must you add to obtain a total volume of 100 mL of the dilute solution? mt

I do not need to see work shown, just the correct exact answers. Please be clear on what the answers are. I will give thumbs up if correct.

4-10

Answer 1

Dillution Equation civo - C₂ V2 = c V ; ; a 2 Initial initial & & final Final concentration volume o c= 6.oom Vi=? C₂ = 0.136 m V2 = 100ML plugging values - 16-00) (V.) = (0.136) (100) Vi= 2.27 m ü 2-3 mL Hence, we perchloric & perchloric need to take 2.27 ml of 6.00m dillute upto 100 ml to get 0.136m. acid solution. c, = 3.0m C2 = ? Vi= 4.47 m2 V2 = 75.0 ML plugging values, a (3.0) (4:47) = (C2) (750) - C = 01179 m ñ 0.180 M Hence, conch of dilluted solution is o 179 m Please Rate.
